Color
- Introduction
- Select contrasting colors for greatest legibility: Readability suffers when there is insufficient contrast between text and background. Maximize legibility by using color combinations that contrast in brightness (such as black and white) and hue (such as purple and yellow).
- Don’t use color alone to convey meaning: Some users cannot see color, while others have difficulties distinguishing certain colors. When using color to convey information, reinforce color with text so people who cannot access color can access the information.
- Allow users to override color settings: Users may need to apply customized color settings to access Web content. Use styles to define colors so users can easily override color settings. Avoid using images, which cannot be customized, for essential page content.
